Abstract
A mixture of fine-particle mineral coal and a fine-particle solid carrier of carbon is stored in a bulk store from which the mixture is withdrawn and continuously blown into a shaft furnace, e.g. a blast furnace. Sufficient carbon carrier is used to loosen the mixture and to prevent it from caking and sticking. A suitable carbon carrier is particulate compost obtained by rotting household refuse or sewage sludge.
